I had this issue with neutron recently. I resolved it by using UUID as the token format in keystone rather than PKI.

A similar bug (here) pointed me in the right direction.

The only change I made to my keystone.conf file was

token_format = UUID

I did not have time to troubleshoot further. I would love a true answer to this question as well. If it is a bug, or a configuration issue.

Question for you. I'm assuming you tried the above with Havana. After changing to above did the token format changed to uuid format ?

Yes. After I restarted the keystone service it was an instant change (and all services on all nodes picked up on the change immediately as well).

thank you Sam. It was supposed to be driven through [driver] section and not through token_format. This surprised me.

I had, if not the same, a similar error. Problem seems to be, that neutron uses api-paste.ini, it's a default. In nova's standard api-paste.ini, at the bottom, there's a comment about a bug. As a solution/workaround "auth_version = v2.0" is added to api-paste.ini, in the "[filter:authtoken]" section.

This worked for me. Here's my issue:
